Abstract: To remove the linear infrared divergences in quenched approximation weinclude the massive fermion loop to the photon spectral function.Spectralfunction of fermion has no one particle singularity if we fix the anomalousdimension to be unity.In the case of $N$ flavour,$N$ dependence of orderparameter is mild which may be due to screening effects.
